Kamar Heatmount Detectors are a valuable heat detection aid that assist in identifying cows ready for artificial breeding. Standing heat behavior in the bovine is the most reliable sign that a cow is ready to be bred. The detectors are a pressure sensitive device with a built-in timing mechanism designed to be activated by standing heat behavior. Glued onto the sacrum (tail head), pressure from the brisket of a mounting animal requires approximately 3 seconds to turn the detector from white to red. This timing mechanism helps distinguish between true standing heat versus false mounting activity.
